Questions on how to Finish pole building

[wastntim]

So I'm in the process of building a pole barn. The first thing I need to say is that I grew up in Chicago and up until a 10 years ago, I couldn't barely tell what a pole barn was. Now, I'm stressing about how to get this building finished. The purpose of the building is to act as a garage/workshop. I'm not looking to make a garagemahal but still want it to look nice and neat.

I ordered a 40'x48' barn which was recently installed. very typical construction with 8' oc posts except I went with perma columns.

Now I am trying to figure out how to finish the building interior. It is my intent to insulate the ceiling and the walls. (I was planning on blown in insulation in the roof and bats in the walls)

For the walls, I have sheets of 3/4" 4x8' sheets of plywood that is coated with a plastic coating. I was thinking about installing a 2x6" board inbetween columns to allow staggering the plywood.

One question I have is whether I should drill the columns to have the electric run behind the plywood for a finished look or just run it on the outside?

The next question is about the ceiling. I initially was going to use 1/2 plywood on the ceiling as I thought metal would cause it to be loud inside. However, I'm starting to rethink that idea, as it seems that metal would seem to be much easier to install.
Anyone want to offer some suggestions on how I should finish this building out?

I'm working on posting some pictures.

I ran 1 1/2'' styrene insulation between the wall strapping and then built 2X4 walls with R13 insulation. If your posts are on 4' centers youre going to need more than 1 stud between. I know the 3/4 will span it. Just my personal preference. Install your elect. in the wall.
For the ceiling what centers are your truss's on? More info would be helpful.

I did the same with 1-1/2" pink insulation foam board between the purlins. Some of the barn (different rooms) I just covered this foam board with 7/16" osb screwed directly to the purlins.

I was concerned with running vertical 2x4 (or 2x6 as OP indicated) studs in the barn. Why, frost heave.
My floors are just a slab without a footer. The floor will rise just a bit in the winter as moisture freezes under the slab. If I have a vertical stud wall that goes to the slab, how do you prevent the slab from lifting the wall and binding with where the wall attaches up top?

The part of the barn that makes up a insulated room, I ran horizontal studs flush with the post. To run it flush I used 2x4's nailed to the side of the post spaced back 1-1/2" from the face of my 4x6 posts.
I used r19 bats inside of this wall covered with plastic moisture barrier then covered with white barn steel. The steel and insulation stops about a 1" from the floor. Not perfect but is what I did.

Here are pics of outside and inside.

If I want to put a metal ceiling in for blown-in insulation, what do I need to do in terms of wood supports between the trusses which are on 8' centers.

I too, have a (unfinished inside) pole barn.

I would suggest that you check with your builder and find out if those trusses are capable of holding up a ceiling, some are not and yours look perty lightweight.

I just bought 150 sheets of 2" thick polyiso insulation on CL.
2" will give me R-14. I plan on screwing it to the girts (walls) and built a wall with 2x4's, which will add up to 5.5" which is the size of the 6x6 posts. For the ceiling, I will attach some nailers onto the wides of the truss top cords and will screw the insulation sheets to them fitting between trusses. I personally don't want to lose the headroom/storage by attaching to the bottom cord. I know R-14 isn't "enough" for the ceiling, but will be plenty with a double barrel stove I'll build. It's a shop, not a living space.

Check your truss specs for ceiling weight. You may be able to screw metal studs perpendicular between the trusses. Hat channel and ceiling after.

Metal liner and surface mounted electric. Much easier to deal with the inevitable changes / new equipment that you will accumulate over the years.

On mine they attached the liner panel right to the undersides of the trusses but mine are 4'oc they used 20' long sheets and I only have one seam in the middle. I went with resessed outlets for a cleaner look.
